If I'm not completely mistaken, all these ringbuffer register have the same offsets over a common base: 0x02000 for the render ring, 0x04000 for bsd on gen5, 0x12000 for bsd on gen6. Can't we just store that base somewhere in intel_ring_buffer and kill all these copy&pasted register access macros? I've played around a bit with this, and most functions become so small it's cheaper to convert them to inlines. This also has the potential make the other functions simpler, perhaps even making them fully generic. Oh, and adding new ringbuffers should becoma way easier, too (blitter ring anyone?). At least my local hacks here where good enough to watch the lotr. If you want I'll push them somewhere, but the patches are not really great and definitely conflict against newer stuff.
